Frequently Asked Questions
How does image detection work?
Our tool analyzes the PDF structure to identify all images on each page. Detected images are highlighted with a clickable overlay so you can easily select which one to replace.
Will replacing an image affect the PDF layout?
The replacement image is placed in the same position as the original. We scale it to fit within the original bounds while preserving aspect ratio.
What image formats can I use for replacement?
You can upload JPEG or PNG images as replacements. Both formats work well for photos and graphics.
Can I replace multiple images?
Yes, you can replace as many images as needed in your PDF. Each replacement is tracked separately.
What if no images are detected?
Some PDFs embed images differently or use vector graphics that aren't detected as images. In these cases, you may see a 'No images found' message.
Is the original image data removed?
The replacement covers the original image with a white background and draws the new image on top. This effectively hides the original content.
Is my file processed securely?
Your files are processed securely by the PDFSub Engine - an isolated server with no internet access. Files are encrypted during transfer and auto-deleted after processing.
